## Mix Redis Subscriber

Redis native protocol Subscriber based on Swoole coroutine

基于 Swoole 协程的 Redis 原生协议订阅库

使用 Socket 直接连接 Redis 服务器,不依赖 phpredis 扩展,该订阅器有如下优点:

- 平滑修改:可随时增加、取消订阅通道,实现无缝切换通道的需求。
- 跨协程安全关闭:可在任意时刻关闭订阅。
- 通道获取消息:该库封装风格参考 golang 语言 [go-redis](https://github.com/go-redis/redis) 库封装,通过 channel 获取订阅的消息。

## Installation

- Swoole >= 4.4

```
composer require mix/redis-subscriber
```

## 订阅频道

- 连接、订阅失败会抛出异常

```php
$sub = new \Mix\Redis\Subscriber\Subscriber('127.0.0.1', 6379, '', 5); // 连接失败将抛出异常
$sub->subscribe('foo', 'bar'); // 订阅失败将抛出异常

$chan = $sub->channel();
while (true) {
$data = $chan->pop();
if (empty($data)) { // 手动close与redis异常断开都会导致返回false
if (!$sub->closed) {
// redis异常断开处理
var_dump('Redis connection is disconnected abnormally');
}
break;
}
var_dump($data);
}
```

接收到订阅消息:

```
object(Mix\Redis\Subscriber\Message)#8 (2) {
["channel"]=>
string(2) "foo"
["payload"]=>
string(4) "test"
}
```
